Description

Air-flotation type deep water material harvester

Technical field:

The utility model relates to a kind of deep water material harvester.Be mainly used in sand, stone, mud, coal, breeze and other material at the deep water bottom are gathered to the water surface.Belong to deepwater dredging, adopt sand, quarrying material and underwater project construction technical field under water.

Background technology:

Before the utility model is made, the collection of deep water sandstone etc. was continued to use submerged pump always and centrifugal pump carries out in the past.They have the following disadvantages:

1, the wearing and tearing of pump are very serious.Large diameter stone directly contacts with tube wall and pump intra vane in last process of moving, and tube wall and pump intra vane very easily wear and tear.

2, the material particular diameter that can adopt of pump is less.Large diameter material by the time very easily smash blade, therefore can not gather larger-diameter material.

3, the power of pump is bigger.The power of pump is directly proportional with the depth of water, and water is dark more, and the power of pump is just big more.

4, the degree of depth of pump collection material is restricted, and can only collect the material of depth of water 50m.

Therefore, such harvester complex structure, the cost height, wearing and tearing are big, and serviceable life is short, the energy consumption height.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, cost is low, wearing and tearing are little, energy consumption is low air-flotation type deep water material harvester is provided.

The purpose of this utility model is achieved in that a kind of air-flotation type deep water material harvester, it is characterized in that it comprises: conduit, outer tube, suction nozzle and air inlet tube, outer tube is placed in outside the conduit, constitute air chamber between outer tube and the conduit, air inlet tube is connected in the outer tube tube wall, suction nozzle is connected in the conduit lower end downwards, and duct wall is densely covered with some air admission holes.Pressurized air enters air chamber between outer tube and the conduit by air inlet tube, and the air admission hole by duct wall enters in the conduit again, and the sandstone material at the deep water bottom etc. are entered by the suction nozzle of conduit lower end, is drawn by the conduit upper end again.

The utility model air-flotation type deep water material harvester is connected with balance pipe on the described outer tube tube wall, and equalizing valve is housed on the balance pipe, is used for the pressurized air in the air chamber between outer tube and the conduit is played the balance adjustment effect.

The utility model air-flotation type deep water material harvester, described suction nozzle lower end is encapsulated with the protection barrier.Be stuck to intercept entering of super large building stones etc.

The utility model device only need be equipped with suitable air compressor machine and can construct.Compare with existing pump class harvester, the utlity model has following advantage:

1, wearing and tearing are little.Material by the floating holder of pressurized air and coating up and move, does not directly contact with tube wall in last process of moving, and friction force is little.

2, the material particular diameter that can adopt is big.There is not gearing in this device, therefore, theoretically as long as can just can collect by the material of conduit caliber.

3, simple in structure, the running reliable, easy to operate.

4, the degree of depth material unrestricted, dark, the shallow water territory of gathering material all can be gathered.

Embodiment:

Among the figure: conduit 1, outer tube 2, suction nozzle 3,

joint flange

4,5 and 6, balance pipe 7, equalizing valve 8, air inlet tube 9,

joint flange

10 and 11, air chamber 12, air admission hole 13, protection barrier 14, tracheae 15, air compressor machine 16, drainage tube 17, sandstone material outlet 18, waterline 19 and sandstone material 20.

Referring to Fig. 1～2, air-flotation type deep water material harvester mainly is made up of conduit 1, outer tube 2, suction nozzle 3, air inlet tube 9 and balance pipe 7 and equalizing valve 8 etc.

Outer tube 2 is placed in outside the conduit 1, constitutes air chamber 12 between outer tube 2 and the conduit 1, and air inlet tube 9 is connected on outer tube 2 tube walls, suction nozzle 3 is connected in conduit 1 lower end downwards, conduit 1 upper end is the outlet of sandstone material, and balance pipe 7 is connected on outer tube 2 tube walls, and equalizing valve 8 is installed on the balance pipe 7.

Referring to Fig. 3, conduit 1 tube wall is densely covered with some air admission holes 13, and the pressurized air that air inlet tube 9 enters in the air chamber 12 is entered in the conduit 1 by this air admission hole 13.

Referring to Fig. 4, suction nozzle 3 is horn-like, and suction nozzle 3 lower ends are encapsulated with protection barrier 14.

Referring to Fig. 5, during use, the air inlet tube 9 and the tracheae 15 of the utility model air-flotation type deep water material harvester join, and tracheae 15 is connected with air compressor machine 16.Conduit 1 upper end and drainage tube 17 join.This device utilizes pressurized air, continuously pressurized air is sent into the drainage tube bottom by tracheae, and Xiang Shuizhong discharges.Because the quality of air is light than water, continuously air by bottom release in pipe of conduit, thereby is extruded drainage tube to the water in the drainage tube.At this moment, the inside and outside of drainage tube will form a pressure differential.The pressure of outside is greater than pressure inside.The size of pressure reduction is directly proportional with the depth of water.Under the effect of pressure reduction, near the import of drainage tube, in certain scope, will produce a very high water velocity.This speed and water and air pressure plutonic direct ratio, under the cutting of high-velocity flow, mud, sand, gravel and other material around the drainage mouth of pipe just held in the palm on the water surface by floating along with high-velocity flow enters drainage tube endlessly.
